Simplifying -2(8t2 + -12t + -3) = 0 Reorder the terms: -2(-3 + -12t + 8t2) = 0 (-3 * -2 + -12t * -2 + 8t2 * -2) = 0 (6 + 24t + -16t2) = 0 Solving 6 + 24t + -16t2 = 0 Solving for variable 't'. Factor out the Greatest Common Factor (GCF), '2'. 2(3 + 12t + -8t2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(3 + 12t + -8t2)' equal to zero and attempt to solve: Simplifying 3 + 12t + -8t2 = 0 Solving 3 + 12t + -8t2 = 0 Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. -0.375 + -1.5t + t2 = 0 Move the constant term to the right: Add '0.375' to each side of the equation. -0.375 + -1.5t + 0.375 + t2 = 0 + 0.375 Reorder the terms: -0.375 + 0.375 + -1.5t + t2 = 0 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + -1.5t + t2 = 0 + 0.375 -1.5t + t2 = 0 + 0.375 Combine like terms: 0 + 0.375 = 0.375 -1.5t + t2 = 0.375 The t term is -1.5t. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5t + 0.5625 + t2 = 0.375 + 0.5625 Reorder the terms: 0.5625 + -1.5t + t2 = 0.375 + 0.5625 Combine like terms: 0.375 + 0.5625 = 0.9375 0.5625 + -1.5t + t2 = 0.9375 Factor a perfect square on the left side: (t + -0.75)(t + -0.75) = 0.9375 Calculate the square root of the right side: 0.968245837 Break this problem into two subproblems by setting (t + -0.75) equal to 0.968245837 and -0.968245837.Subproblem 1
t + -0.75 = 0.968245837 Simplifying t + -0.75 = 0.968245837 Reorder the terms: -0.75 + t = 0.968245837 Solving -0.75 + t = 0.968245837 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + t = 0.968245837 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + t = 0.968245837 + 0.75 t = 0.968245837 + 0.75 Combine like terms: 0.968245837 + 0.75 = 1.718245837 t = 1.718245837 Simplifying t = 1.718245837Subproblem 2
t + -0.75 = -0.968245837 Simplifying t + -0.75 = -0.968245837 Reorder the terms: -0.75 + t = -0.968245837 Solving -0.75 + t = -0.968245837 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + t = -0.968245837 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + t = -0.968245837 + 0.75 t = -0.968245837 + 0.75 Combine like terms: -0.968245837 + 0.75 = -0.218245837 t = -0.218245837 Simplifying t = -0.218245837Solution
